A woman who was refused a drink at city centre bar allegedly responded by undertaking her own dirty protest, staff at the venue claim.
The unidentified drinker is said to have reacted angrily - and disgustingly - after being refused shots at the swish bar in Newcastle.
Chronicle Live reports the punter allegedly wiped her backside with toilet roll before scattering pieces of used loo roll around the venue - including leaving one sheet under a cushion.
Bosses at Tiger Hornsby have condemned the "absolutely disgraceful behaviour", which is said to have happened on Thursday night.
Staff, who bosses claim were forced to don gloves to clean it up, were left horrified - and shared CCTV footage with other venues to warn them about what happened.
